It's not hard to get donuts right. I thoroughly enjoy donuts of the Krispy or Dunkin variety and can't complain. However, after trying Biagio's donuts, you can really tell the difference in quality between a place like this and a chain like the aforementioned.
Their crullers are melt-in-your-mouth good. Light, fluffy, flaky, and almost creamy at the same time. They have red velvet cake donuts, which are also very good (though the icing could be better). Their donuts at least FEEL light, in that I could eat 1 or 2 more, and I don't feel like crap afterwards. The same can't be said for others I have tried.
I just wish it was closer. The only time I get to have Biagio's donuts is when my coworker brings them in. Moderation is probably a good thing though.
